If you have auto, or the fan curve enabled, the sliders in precision mean nothing. If you move a slider you have to save and apply then they will take effect.

I'll update this post when the images get fixed if it changes my comment.

Which version of precision x are you running? If you go to options and click check for updates, it will give you the current version after it checks. The 30xx series standalone on top of forums is what is recommended, 1.1.0.2

Edit: Aren't there only 3 fans on the FTW3 Ultra?? Why is it showing 4?

Spyle
It's the latest version. It has 4 because I used the connection ext fan connection.
 
I shut down my PC and started it back up, they are now working independently again but FAN 3 is still messed up. The beginning it has the exact same fan curve as 1 and 2, while they stay near a solid RPM, 3 bounces from 0 RPM to 1050. After that I set it to 100%, 50%, and 35%. Again all over, so I'm guessing either Fan 3 is faulty or it's something else entirely (seeing as what was happening before with 2 controlling 3/4..)

Can you try and test everything without the ext fan attached? Reinstall PX1 after removal of the fan. You might have found a bug with the current version and utilizing an extra fan. If the above doesn't help, definitely post in the topic for the latest PX1.

Disconnected it and reinstalled PX1, problem still persists

I see the exact same behavior on FAN 3 

Spyle
Auto and curve control are disabled. 
 
Using Curve Control, FAN 1 and 2 seem to be fine, but FAN 3 is all kinds of wonky
 
 

Running a 3090 FTW3 Gaming here and I've sent in a ticket to EVGA support for this exact issue plus my card's FAN 3 has a high-pitched whine when it runs.
 
The bounding RPM issue is a bit less pronounced on my card than yours but it is still there (see the screenshot with comparison of FAN 1, 2 & 3). I also see the odd reporting within Precision X1 on the fan speed screen. Running latest Precision X1 for 30 series, firmware updated, happens both on OC (higher fan curve) vBIOS & Normal.
 
Here's a clip I made of my card's FAN 3 whine:  https:// www.youtube.com/watch?v=64KUwt3Jh18

You'll need something that can handle pretty high frequencies. This whine happens only when FAN 3 runs, turning off the fan removes the whine entirely even if I push the card, though I don't run it under load for long as it gets pretty hot even with just the single fan disabled.


Since my gaming PC isn't my main driver I can deal with the whine somewhat, I'm mostly concerned there may be some deeper underlying issue with the fan, the controller, etc. given the other issues present.

Guessing in the screenshot Fan 3 is at about 25%? Mine looks almost exactly like yours if I set it to that.  Mine seems to start jumping between 0 and 1100 RPM only when around 20% or lower, probably because the low end of the fluctuation isn't enough power to keep it spinning at all. So for now I've just set the min at 30%.  Not a perfect line like 1 and 2 but at least it isn't bouncing between 0 and 1100, you can actually see the blades slowing down and speeding up constantly when it does that.

Yeah 20% is my curve baseline. I also noticed the same odd startup / slowdown issue on mine. Very apparent when FAN 1 & 2 are solid at a given RPM and 3 is all over the place.
 

jPup omgWait, I see you can set static speeds for each fan... but is it possible to program unique fan curves for each fan in PX1?

Not 100% sure if it was possible in older versions (I think it was?). I've attached my customized fan curve as a reference. Will change it once I take it off my open-air stand and move it into a case since temperature will vary greatly in that environment. Just wanted something stable for now while I work out the kinks. :)

I can check with our VGA/Software teams tomorrow to see if they have an idea, but you likely won't hear back until Monday at the earliest.
 
I know you guys have tried to remove the software, but I'd suggest to do that one more time.  After removing the software, go to %LocalAppData%\EVGA_Co.,_Ltd\ then delete all setting files that start with "PrecisionX_x64".
 
Reboot, then reinstall PX1 and try again.
 
I don't know if you guys had PX1 installed before, but if so, maybe there's an issue with profile corruption.  Removing the profile settings might help. 
 
Let me know if that fixes it.

Hi Lee,
Thanks for checking up on this for us, totally understand that this may not be the highest priority defect atm given so few of us 3090 users have reported it.
 
I repeated the install process and had it wipe profiles and was able to confirm that the EVGA_Co.,Ltd folder was deleted inside the AppData/Local subfolder of my user. I also checked Roaming and the EVGA folder was empty as well. Rebooted and reinstalled, but I'm still getting the same behavior from FAN 3 both the RPM fluctuations and the fan whine.
 
I had similar concerns with profile corruption between versions given that the newer PX1 only supports the 30 series at this time. Before installing the new card I uninstalled the previous PX1 and had it remove profiles but I did not verify the AppData folders were cleared out like I did this time.
 
Something I do want to add regarding my initial boot of the 3090 w/the new PX1: Upon first boot with the new PX1 and 3090 the switch was already set to OC and not Normal when the firmware was updated. I'm not sure if this matters or not during the flash process. I do apologize I didn't mention it sooner, it completely slipped my mind. :(
 
Thanks again for looking into this!

Nice to know I'm not the only one having this issue, only fan 3 under low % Would the RPM jump around from 1000 RPM to 0.

Spyle and Monolyth, can you take screenshots of the information page?  Just click on the "I" next to the PX1 version.  Thanks!

 
Here you go sir!

I did manage to find out what causes Fan 2 to control the speeds of 3 and 4 rather than follow their own setting.. It happens if my PC goes to sleep with PX1 open, when it wakes this happens every time. Restarting PX1 fixes it immediately.

I have a beta PX1 version for you guys to try to fix the fan issue.  I'll PM you guys shortly.

Is this issue only happening on 3090 FTW3 or what about 3080 FTW3?  (Mine comes Monday is why I ask :))

Is this 'beta' version newer than the released version of 1.1.0.2?  My third fan has been driving me nuts since for about a week.  Its bouncing around 1200-1300RPMs while 1 and 2 are stable at 1250.    3090 FTW3 Ultra.

I'm in the same boat, fan 3 is driving me nuts. I sent a DM to EVGATech_LeeM about getting access to the beta version.
